What is KURALON?

  • KURALON, a synthetic fiber made from polyvinyl alcohol fibers (PVA), was developed in 1939 by a team led by Professor Ichiro Sakurada at Kyoto University.
  • In 1950, Kuraray became the first company in the world to mass produce Japan's first synthetic fiber, named KURALON.
  • Among synthetic fibers, KURALON features the highest hydrophilic properties; superior ultra-high strength and weather resistance; and strong resistance to alkali and acidic substances.
  • Demand for KURALON as a reinforcing fiber in cement to replace asbestos has increased in the European and Japanese construction markets. In addition, Kuraray expects demand to grow in Southeast Asia, Eastern Europe and Central and South America.
  • KURALON production base: Kuraray's Okayama Plant (Minami-ku, Okayama City)
  • In 2010, KURALON was recorded in the registry of important historical materials of industrial technology (Epithet: Technological Legacy for the Future) by the National Museum of Nature and Science.
